He's been banned from playing cricket for 12 months after allegedly masterminding a ball tampering plot, involving sandpaper.

But David Warner has plenty to keep him busy, trading in his cricket bat for a drill and hard hat.

On Thursday the disgraced Australian cricket vice captain was busy at work on the building site of his under-development mansion, located in the beachside Sydney suburb of Maroubra.

David's wife, Candice Warner, shared a video to Instagram of David hard at work using a drill at their under-construction luxury family home.

The disgraced cricketer was all smiles as he got to work, sporting a hard hat that read 'Project Manager' and 'Apprentice Celebrity.'

Candice also posted a photo of the couple's daughters - Ivy Mae, three, and Indi Rae, two - wearing hard hats at the building site.

"A couple of cuties on site this morning checking out the progress of their bedrooms," she captioned the photo on Instagram, also adding the hashtag '#dreamhome.'

The couple are building a $10 million mansion on a block of blue ribbon land overlooking Lurline Bay, which was purchased by David and Candice for $4 million in 2015, The Australian reported last December.

According to nine.com.au, the family of four are currently living in a nearby Maroubra home they purchased for $2.3 million in March 2017 as they build their dream five storey home.

Last month, an investigation by Cricket Australia alleged David had masterminded a plot to cheat during the Third test against South Africa.

He was handed a 12 month ban after the sporting body found David had instructed junior player Cameron Bancroft on how to tamper with a ball using sandpaper.

Cameron received a nine month ban while cricket captain Steve Smith was handed a year long sanction for his knowledge of the plot.

Prior to the ball tampering incident, David had been subjected to sledging which referred to Candice's infamous toilet sex romp with Sonny Bill Williams in 2007.

Candice, who was comforted by PR queen Roxy Jacenko at David's press conference, has since said she blames herself for what happened.

'I feel like it's all my fault and it's killing me - it's absolutely killing me,' she told The Daily Telegraph.
